广东省旅游生态安全时空测度及障碍因子诊断
Spatiotemporal Measurement and Diagnosis of Obstacle Factors on Tourism Eco-security in Guangdong Province
摘要
Abstract
Based on pressure-status-response (PSR) model,we chose Guangdong Province as the sample and established the evaluation systems of tourism eco-security,then applied entropy weight and synthetic evalua tion model to analyze spatiotemporal variation characteristics of tourism eco-security in Guangzhou,finally adopted obstacle degree model to diagnose the main limiting factors on tourism eco-security.The results are shown as follows.(1) During the period from 2005 to 2014,the comprehensive tourism eco-security index showed the rising trend,and the security level raised from the risk grade to the relatively safe grade.(2) Besides Jieyang,tourism eco-security levels of other 20 cities have improved from 2005 to 2014.(3) From the index layer,the biggest obstacle factor of tourism eco-security in Guangdong Province is urban living sewage treatment from 2005 to 2008,the biggest one is solid waste discharge from 2009 to 2010,and the biggest one is urbanization rate from 2011 to 2014,and the main influence factors shifted from factors of environmental economy to the ones of social economy.From the point of target layer,now pressure system becomes the main factor to hinder the promotion of tourism eco-security level in Guangdong Province.关键词
